Wolf Hiding Slot by Evoplay

Mystery symbols land in stacks of four, covering an entire reel column. When they hit, they flip open to reveal matching regular symbols, wilds, or Full Moon triggers. And then they do something unusual - on the next spin, those mystery positions nudge down by one row while the remaining reels spin normally. This repeats each spin until the stack slides off the bottom of the grid. A single stack landing gives you four consecutive spins of guaranteed symbol reveals on that reel.

The Full Moon feature fires when a mystery stack reveals Moon symbols instead of regulars. Each position in the stack then independently spins and lands on either a coin value (1x to 2,500x bet) or a free spins symbol. All coin values are totaled and paid out immediately. If three or more free spins symbols land across the Full Moon reveal and the main grid combined, the free spins round triggers on top of the coin payout.

Free spins start with reels two and four fully loaded with mystery stacks. A win multiplier begins at 1x and climbs each time a Hidden Feature triggers - meaning each time a mystery stack reveals and starts its nudge cycle, the multiplier ticks up. The round has no fixed spin count. It keeps going until all mystery symbols have nudged off the grid, so the length depends entirely on how many new stacks land during the round.

Four animal warrior characters serve as high-paying symbols - wolf, fox, cat, and a masked figure - set against a moonlit forest with a dark blue palette. The Wolf Hiding Bonus Buy variant adds direct access to the free spins for players who want to skip the base game grind toward 30,000x.
